[[https://www.mediawiki.org/wiki/Extension:Cognate|Congnate extension]] should be converted to use manifest version 2 in its extension.json file.
In extension manifest version 1, documentation was made like this:
```lang=json
"config": {
"@CognateDb": "The database to use for storing Cognate data. The default is to use the db of the current site.",
"CognateDb": false,
"@CognateCluster": "The cluster to use for storing Cognate data. The default is to use the cluster / server of the current site. See $wgLBFactoryConf.",
"CognateCluster": false,
}
```
This documentation can now be done with "description" field available in `manifest_version: 2` like this:
```lang=json
"config": {
"description": "The database to use for storing Cognate data. The default is to use the db of the current site.",
"CognateDb": false,
"description": "The cluster to use for storing Cognate data. The default is to use the cluster / server of the current site. See $wgLBFactoryConf.",
"CognateCluster": false,
},
```
The maintenance script [[https://www.mediawiki.org/wiki/Manual:UpdateExtensionJsonSchema.php|maintenance/updateExtensionJsonSchema.php]] semi-automates this conversion and is recommended to be used
